Publications

We found that many problems in computational linear algebra and the accuracy of numerical solutions can be rigorously verified at computing costs associated with an approximate solution. This verification speed is very fast and offers numerous applications.

We have also proposed the idea of error free transformations of floating point numbers, which makes it possible to construct adaptive numerical algorithms that generate numerical solutions of the required accuracy at near-minimal computational cost. As applications, we have establishing failproof computational geometric algorithms; developed tools for computer-assisted proofs for differential equations and adaptive fast inversion algorithms for ill-conditioned matrices; and verified linear programming algorithms (involving the verification of optimum points) and the accuracy of nano-optics simulations. Very large and sparse linear equations of more than 1 million dimensions can now be solved with verified accuracy using clustered computers based on our rounding mode controlled verification method.

The list of papers including these results are shown in the following list:
